The Curve no sound call problem
OS 4.5 is coming out real soon and it'll address that issue, as well as add HTML email capability.
VZW is currently in the process of approving the software release, give it 2-3 weeks.
My curve gets dead audio too, but I'm not sweating it. A fix is on the way.

Even though it only happened one time to me I downloaded the "softreset" application (google it, it's free). This let's you reboot your blackberry without pulling off the battery to fix this issue when it occurs and also in case you need to reboot after uninstalling/installing an app.
There IS an OS update on it's way. Soon.
